This quantity names a form of viscosity that only applies to fluids that can have flows with nonzero divergence; those fluids are thus called compressible. This quantity is raised to the polytropic index in the relation that constrains polytropic processes. The parameter (*) b in the van der Waals equation of state exists because nonideal gas particles exclude some amount of this value. Avogadro's law states that this value is constant for a set amount of ideal gas and is equal to about twenty-two point four liters per mol. For 10 points, name this quantity proportional to the cube of length.
